It's not too early, and it's not too much time. They are going in their own rhythm. They love each other so much <3 they don't need to marry to know that. Ev'rything comes in the right time, and they're happy, so.. Why hurry up the things? :3
Well gaga is a very open person but when it comes to her family and love life she is very reserved so they could've but I think gaga would tell us I think but I really don't know anyway they should get married there such a beautiful couple
Backstage on monday in Oslo, we asked her if they would get married, her answer was; if he fucking asks me! :) but she also said that she is happy now, so why get married yet? :)
